PURPOSE
library(plotly)
library(ggplot2)
library(ggvis)
EXAMPLES
1. ggplot2

Pros
- super-control over plot features and format
- uses grammar of graphics
- lots of usage and support
- good skill level already attained, with lots of home-made examples
Cons
- no further ‘official’ development - basically abandoned in favour of ggvis
- no built-in interactivity
- can be cumbersome code
- can’t easily download
Use
- static charts, including R Markdown HTML files
- maybe with Shiny, but probably choose alternatives below
2. ggvis
Pros
- designed for more interactivity than ggplot2 (although require shiny)
- defaults to cleaner style than ggplot2
- takes advantage of pipe (%>%) and integrates with dplyr
- easy export/download
Cons
- interactivity requires Shiny
3. Plotly
Pros
- full-on library of interactive charts
- can embed charts with some interactivity in R Markdown HTML files
Cons
- interactivity is limited to zooming, hover labels (which is cool but not sufficient)
- for shiny, requires library on shiny server - compatible version
- recent update (v4.0) not backwards compatible, breaking older charts
Use
- embed in R Markdown HTML for limited interactivity
- possibly with shiny
